Modify Tracks in OpenCPN

[matthias-mw]

Hi Together,


I am new to OpenCPN and use is for the first season. It works great so far and I am still learning about all the features.
I just didn't find a way to edit single points a the recorded track. My problem is, that during a long passage, my GPS somehow got some weird location info. So my track has some ugly spikes all over the screen. These single points I want to delete?

Is there a way? Where is the track data written to? Is the a file that can be edited?

Thanks in advance

Properties for a track can be seen by the right click menu or Tools->Route & Mark manager but here is no way to edit single marks.

Routes, tracks and marks are stored in "navobj.xml" in the same folder as the log file. (On Win normally "C:\ProgramData\opencpn")
Theoretically this file can be edited if you're good at handling XML code. A safe copy is created once every O session called navobj.xml.1 (up to 5)

If your false positions are very short you may benefit from increase the "Filter NMEA Course and speed data" handled in Options->Connect.

Also be sure to use latest OCPN release. I think there have been some attempts to sort out similar not relevant positions. In any way it's discussed before.
